The impact of lithium batteries on the UPS power system and the advantages of lithium battery UPS. Lithium batteries are everywhere in life, from mobile phones, cameras to electric bicycles, electric vehicles have lithium batteries, in the past few years, lithium battery technology and The structure and structure have a great evolution and evolution, and its performance, safety and cost have been significantly improved. Lithium battery UPS has gradually begun to be accepted and favored by customers.
First, the impact of lithium batteries on the UPS power system
Many UPS power systems still use traditional lead-acid batteries, and their performance has hardly changed much in the past few decades. In addition to data center industry applications, new energy storage technologies for smart phones and electric vehicles have made research progress. Therefore, lithium battery UPS will adopt this better energy storage technology.
Second, the replacement of lead-acid batteries by lithium batteries is inevitable
Lithium battery can be said to win in the comparison with the technology of lead-acid battery. The main obstacle to the large-scale popularization is cost. At present, the purchase cost of lithium battery is about twice that of lead-acid battery, which is also hindering the lithium battery in the data center field. The most important reason for the wide range of use. In fact, considering the need for the BMS of lead-acid batteries, and the long-life design of the lithium battery pack can greatly reduce the cost and maintenance cost of replacing the battery, the lithium battery pack has certain advantages on the TCO. From the perspective of long-term use, lithium battery UPS can save 10% or more. With the further popularization of lithium batteries, the cost will continue to decline in the future, and the final replacement of lead-acid batteries by lithium batteries is inevitable.
Over the years, the safety of lithium battery packs has made great progress. The changes in chemical materials and packaging have made the properties of lithium batteries more stable, the production process and process are mature and reliable, and the materials used are more durable. Testing and field validation to prevent overcharging or overheating of lithium batteries. Today, hundreds of millions of portable electronic products, such as smartphones and electric vehicles, use lithium batteries in large quantities, which proves the safety of lithium batteries.
Third, the advantages of lithium UPS compared with traditional lead-acid batteries:
1. Smaller size: Compared with lead-acid batteries, it provides only one-third of the space in the case of providing the same power. Helping customers increase the deployment scale of existing IT systems while reducing heat dissipation requirements. Save investment costs and operating costs.
2. Longer life: The average working life is 10 to 15 years, while the lead-acid battery can last only 4 to 6 years. The longer shelf life effectively reduces the cost and maintenance burden of battery replacement.
3. Battery Management System (BMS) management: The microprocessor, sensors, switches and related circuits automatically collect and report the required data to accurately understand the health of the battery system and further reduce the maintenance burden on the staff. The system also helps protect the battery from damage and prevents voltage from being too low or discharged. The BMS system provides users with accurate information on UPS and battery status, health status and effective runtime.
4. High and low temperature adaptability, can be used in the environment of -20 ° C -60 ° C, after the process treatment, can be used in -45 ° C environment.
5. Green, no matter whether it is produced, used or scrapped, it does not contain any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.
6. No memory effect, regardless of the state of the lithium iron phosphate battery, can be used with the flash, no need to put the first fully charged.
Fourth, the future market prospects of lithium batteries
Lithium batteries may have a greater impact on the data center industry in the future, as more and more companies are looking to adopt an open computing-based architecture, and they will specify a lithium battery as the power supply unit for the server's power supply in the rack.
It is reported that the lead-acid batteries in the replacement of UPS in foreign lithium batteries have begun to be accepted by more enterprises. In some countries (such as South Korea), the replacement of lead-acid batteries by lithium batteries is very fast, and lithium batteries account for up to 30%. A full lithium battery UPS system like Shinhan Bank appeared.
